Pulsafeeder GreenLine Metering Pump, 7.9 GPH @ 145 PSI, 115/230 V, with PVDF wet end and Leak Detection
The GreenLine‑GLM DM2A1FC‑L is a mechanically actuated diaphragm metering pump designed for accurate and reliable chemical dosing, especially in corrosive or aggressive chemical environments. This model features a PVDF liquid end for superior chemical resistance, a 115/230 V TEFC motor, and a factory leak detection package that includes a double diaphragm, pressure gauge, and a 24 VDC leak detection switch. Rated for 7.9 gph (30 lph) at 145 psi (10 bar), the DM2A1FC‑L is ideal for water treatment, chemical processing, and industrial applications requiring enhanced containment and safety.
